Description

具有驱蚊虫功能的光学板材的制作方法
技术领域
本发明涉及光学塑料板材领域,特别涉及一种具有驱蚊虫功能的光学板材的制作方法。
背景技术
传统的驱蚊虫光学塑料板材是利用可驱蚊虫的植物精油:薰衣草、肉桂叶、香茅、百里香、殴薄荷、柠檬香茅等精油,利用配方工艺生产出精油母粒后,按配比与塑料混合,生产出光学板材,使板材上含有蚊虫不喜欢的精油气味,以达到驱蚊的效果。
但是,利用传统工艺生产出来的驱蚊虫光学塑料板材有以下缺点:1、利用液体精油生产母粒时:液体与固体混合造粒工艺控制难度高,高浓缩精油母粒难以实现;使用成本高。2、液体精油普遍耐温性较差、容易挥发、高温容易蒸发,生产母粒时精油流失率高达20%~30%,精油利用率低,成本高。3、利用精油母粒生产的板材由于精油的易挥发性,时效短,驱蚊效果容易失效。4、精油具有一定的酸碱度,直接与塑料接触会引起精油与光学塑料板材化学反应,降低板材寿命。
发明内容
基于此,有必要提供一种具有驱蚊虫功能的光学板材的制作方法,包括如下步骤:
植物精油微胶囊制备:对液态的驱蚊虫植物精油进行微胶囊化处理,得到芯材为驱蚊虫植物精油的,呈粉状的植物精油微胶囊;
母粒制备:将得到的植物精油微胶囊与相容剂、热稳定剂、分散剂和光学材料载体混合均匀后,对其进行挤出造粒,得到驱蚊虫母粒;
板材制作:使用光学塑料板材加工工艺对得到的驱蚊虫母粒进行加工,得到具有驱蚊虫功能的光学板材。
本发明中,驱蚊虫植物精油为具有驱蚊虫效果的植物精油,本发明通过微胶囊技术将驱蚊虫植物精油包裹在微胶囊中,并将植物精油微胶囊按配比与塑料混合,生产出光学板材,可以使得该光学板材具有驱蚊虫的效果。
其中,本发明采用植物精油微胶囊进行驱蚊虫母粒的制备,相较于直接使用驱蚊植物精油制备驱蚊虫母粒,本发明能更容易地将驱蚊虫植物精油混合在驱蚊虫母粒中,同时,还可以减少母粒制备过程中驱蚊虫植物精油的挥发损失;另外,将驱蚊虫植物精油包裹在微胶囊中,可以减缓植物精油微胶囊的挥发速度,从而可以长效保持光学板材的驱蚊虫效果。
其中,植物精油微胶囊与相容剂、热稳定剂、分散剂和光学材料载体的混合过程可以采用高速混合机完成,挤出造粒过程可以采用双螺杆挤出机完成。
优选的,驱蚊虫母粒包括如下重量份的组分:植物精油微胶囊5%-30%、相容剂0.01%-0.5%、热稳定剂0.01%-0.5%、分散剂0.01%-0.05%、光学材料载体68.5%-94.97%。
优选的,所述驱蚊虫植物精油为薰衣草精油、肉桂叶精油、香茅精油、百里香精油、殴薄荷精油和柠檬香茅中的一种或几种的组合物。
优选的,所述驱蚊虫植物精油为柠檬香茅精油。
其中,柠檬香茅精油具有较好的热稳定性,可以使其在微胶囊化的过程中,保持其物理化学性质的稳定,同时,光学板材的使用环境一般具有较高的温度,柠檬香茅精油较好的热稳定性还能减缓其在光学板材中的挥发速度,进而可以进一步地延长光学板材的驱蚊虫效果;另外,柠檬香茅精油除了驱蚊虫的效果还具有杀菌、除臭的作用,因此采用柠檬香茅精油制作而成的光学板材除了具有驱蚊虫的效果之外,还具有良好的杀菌、除臭效果。
优选的,所述植物精油微胶囊的壁材为聚苯基硫醚。
其中,柠檬香茅精油和苯基具有良好的相容性,因此,采用聚苯基硫醚作为微胶囊的壁材,采用柠檬香茅精油作为微胶囊的芯材,可以有效简化植物精油微胶囊的微胶囊化过程,能有效降低其工艺难度和工艺成本。
优选的,所述植物精油微胶囊的直径为1-500um,所述壁材的厚度为0.5- 150um。
优选的,所述光学材料载体为PS塑料或者PMMA塑料。
优选的,光学塑料板材加工工艺为:将驱蚊虫母粒与PS塑料原料或PMMA塑料原料混合在一起得到驱蚊虫原料,将光扩散母粒与PS塑料原料或PMMA塑料原料混合在一起,得到扩散原料,并将驱蚊虫原料和扩散原料经同一模口挤出,得到呈AB结构或者ABA结构的光学板材,其中,驱蚊虫原料形成光学板材的A层,扩散原料形成光学板材的B层。
其中,当驱蚊虫母粒中的光学材料载体为PS塑料时,驱蚊虫母粒和扩散母粒中的塑料原料则对应为PS塑料原料,当驱蚊虫母粒中的光学材料载体为PMMA塑料时,驱蚊虫母粒和扩散母粒中的塑料原料则对应为PMMA塑料原料,即与驱蚊虫母粒和扩散母粒混合的塑料原料为与驱蚊虫母粒中的光学载体材料相同的塑料原料。
其中,将驱蚊虫原料和扩散原料经同一模口挤出,即可得到分层的光学板材,使得由驱蚊虫原料形成的A层位于光学板材的表面,可以在使得光学板材具有驱蚊虫效果的同时,减少驱蚊虫精油的使用,进而能有效降低驱蚊虫光学板材的成本。
优选的,所述A层的厚度占所述光学板材的厚度的20%-30%。
优选的,所述驱蚊虫原料包括如下重量份的组分:驱蚊虫母粒1%-6%、PS塑料或PMMA塑料94%-99%,所述扩散原料包括如下重量份的组分:扩散母粒1%-4%,PS塑料或PMMA塑料96%-99%。
其中,当驱蚊虫原料中的驱蚊虫母粒的光学材料载体为PS塑料时,驱蚊虫原料和扩散原料中的塑料原料对应为PS塑料原料,当驱蚊虫原料中的驱蚊虫母粒的光学材料载体为PMMA塑料时,驱蚊虫原料和扩散原料中的塑料原料对应为PMMA塑料原料。
下面结合上述技术方案以及附图对本发明的原理、效果进一步说明:
本发明采用植物精油微胶囊进行母粒的制备,相较于直接使用驱蚊植物精油制备母粒,本发明能更容易地将驱蚊虫植物精油混合在驱蚊虫母粒中,同时,还可以减少母粒制备过程中驱蚊虫植物精油的损失;另外,将驱蚊虫植物精油包裹在微胶囊中,可以减缓植物精油微胶囊的挥发速度,从而可以长效保持光学板材的驱蚊虫效果。
